How did you get the idea to trim the cases?

Franchise, I got the idea to use the second crimp line from the 10.9 article I read which utilizes the second crimp line of the 300 XTP. Setting the bulletâ€™s OAL out to 1.75 means less bullet jump and I feel like it was one of the factors in my SRH shooting sub 1.5in groups at 100 yards. When I saw the Magtech 240gr bullets with the second crimp line I immediately thought of extending the bullet out. I did some ruff estimates and quickly realized that it would be too long for the 44 Mag brass. Soâ€¦ letâ€™s try the 44 spâ€¦ Not only did it work but it also gave me 1/10th of an inch more powder capacity. (roughly .830 to .920â€¦ ok so 90/100thsâ€¦) Well, the goal was to turn the OAL into 1.74. I did a few more measurements, trimmed some 44 Mag brass and set up my extra set of dies. The end result is just over a full inch of powder capacity,(1.01) even with the shortened brass. That is over 15% more powder capacity than the 44 Mag. My goal is to hit 1400fps. At that, 1400fps, it should have less kick than a standard 240gr at the same velocity. My main goal is accuracy. I just got done loading up 15 different experimental rounds. 6 of those loads were the new creation. I will let you know how the mutt did. LOL

John, I havenâ€™t had a chance to shoot anything yet. Bug did shoot a nice pig with oneâ€¦ dropped that pig like it was hit with a sledge hammer.

Best regards

Duane

Very good idea IMHO...last summer I trimmed a bunch of .454 brass for a similar reason; to utilize a certain bullet's crimp groove.

Only thing is ya gotta be organized enough to keep those cases separate; and that is not one of my strong points...
